To all whom 'it may conccri:

LEWIS McLELLAN, OF GORHAM, MAINE.

Letters Patent N 89,419, dated April 27, 1869 IMPROVEMBNT IN cULmARY-BoILBRs;

The Schedule re'en'ed to in thes Letters Patent and making part of the same.

-Be itknown that I, LEWIS MGLELLAN, of Gorhan, in the county of Cunberland, and Sta-te of Maine, have invented a new and useful Improvement in Cooking Gauned Corn, and other articles; and I do hereby declare that the following is a full', clear, and exact de` scriptiou thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanyiug tlra\vings,tb'niing part of this specihcation.

This inrentiou rclates to a new' and improved device for cooking, boiling, or preparing corn, and other articles -which 'rt is designed to pr srve in lnrmeticallysealed cans. And

It consists in the -combination of the stcam-trap with the boiler, or vessel of peculiar Construction, whcrein is placed the corn, or other article to be cooked by steam', at a temperature higher than 212 or by boiling under prcssure, as may be deemed most proper for the article to be prepared, as will be hcreinafter more full y described.

In the drawing Fignre 1 rcpresents a vertical section of the vessel, constructed according to my iuvcntion, provided with a rack, or removable shelves, on which the pans containing the cans of corn, or other article, are placed for'cooking.

Figur-e 2 is a vertical section of the steam-trap.

Similar let-ters indicate like parts.

A rcpresents a boiler, or vessel, of any desired shape and size, and constructed of any suitable material.

B is a fiange, which allows the vessel to be suspended from a floor, or shelf, as seen in the drawing in red lines.

C is the door, which is hinged to the under side of the fiange, or head (I, which, when closed, is made stcau-tight with suitable packing.

E is a bail, the cnds of which rest upon the flange d.

F is a S(' 'e\\'-ll()(k, which llOOkS on to a w'ist in the door and passes up through the bail, with a knob-nut, g, upon its nppcr end, so that, when closed, the door canbe drawn ti ghtly up, and made stean-tight against the lower side of the fiange (Z.

H is a 'acl: of shclvcs, which shelvcs maybe more or less in number, and of any suitable size, either fixed or adjustable.

z' rcprcscnts theshclves, and

j, the st-ays, or bars, by which the shelves are supported.

The shelves contain the pans of corn, or other articlc in cans, to be cooked, and the rack containing th cans is lowered down into the vessel, and the door is closed.

Steam is admitted through the apcrtnre marked m. 'n is an orifice, near the bottom of the vessel, for the discharge of the water of eondensation, which is provided with the valve,` or trap I, to prevent the es-` cape of steam, and so that water may be retained in' float is raised by the water of condensation, the valve h is also raised snfficiently to dischargc such water.

It must be observed that the wat-er will be dischargcd before it reaches the level of the pipe O.

When the corn, or other article, is sufficientlycooked, the vessel is opened, and the rack, with the pans and cans of corn, is hoisted out.

This vessel may be placed over a fire, in a suitablyconstructed furnace with water, where the corn, or other article, may be subjected to any desired degree of leat, but I prefer the use of steam, ntrcdnced as described, as, by the steam-process, the corn changes color less than when it is cooked by boiliug in water.

By cooking the corn, Cte., in a closed vessel, under prcssure, the time required for the process is greatly lessened, and the article less injured than by boiling in the ordinary manner.

I claim as new, and desire to secure by Letters Patcnt- The trap I, in combination with the vessel A, constructed as described, and provided with the fiange B, steam-supply opening m, the linged cover O, bail E, hook F, nut g, and rack H, as herein set forth, for the purpose specified.

' LEWIS MCLELLAN.
